“…The reverse (figure 1) represents three togate men advancing left, two of them holding an axe on the shoulder, possibly inspired by a silver denarius issued in 54 BC by Junius Brutus [2]. The kosons are considered as the only gold coins issued by the Dacians.…”

“…In a previous study, various types of gold coins discovered in Romania have been analyzed by energydispersive X-ray fluorescence (XRF) using radioactive sources ( 238 Pu and 241 Am) and by proton activation analysis (PPA) [2], which gave extensive results on their basic composition. The present study aims at more detailed insight into the fingerprint and provenance of Dacian kosons.…”

Studies by Synchrotron Radiation -X-Ray Fluorescence (SR-XRF) for the search of the presence of trace elements like Sb, Sn, Te and Pb in archaeological metallic objects found on the territory of Romania -old coins and Bronze Age jewelry, aimed to determine the provenance of the gold used in their manufacture. The results are compared with the detailed elemental composition of alluvial or primary gold samples, obtained by the same technique. This work attempted to establish the origin of the gold used for the mint of two different types of koson coins. We found that the kosons with monogram are made of refined gold, while the one used for the kosons without monogram is mainly alluvial. The gold used in the manufacture of the Calarasi Vulchitrun-type disk and the Tauteu hair ring is also of alluvial origin.

This paper reviews the use of X-ray fluorescence spectrometry (XRFS) for non-destructive studies of valuable metallic objects in the fields of jewelry, archaeology and art, as well as its application in the analysis of coatings and solutions, due to the interest of these issues in jewelry manufacture. The general features of the technique as well as the most outstanding results obtained in the commented fields are described, taking into account the most important sources of error, mainly in the case of samples that have suffered corrosion processes.

This study intends to clarify the metal provenance of gold archaeological items using the variation of the Au-Ag ratio and the presence of trace elements as Sn, Sb, Te, and Pb, concentrating on gold Dacian Koson coins, recovered recently. It also extends the area of our investigations to the copper provenance of Bronze Age artifacts-axes, sickles, and celts-found on Romanian territory. The experiments were performed by micro-SR XRF at BESSY Berlin, at the BAM-line facility. Two types of coins (Koson, with and without monogram) were analysed. The conclusions we reached were that most of the monogram coins are made from refined gold (3-5% Ag, less than 0.5% Cu), while the without monogram coins are made from native Transylvanian gold (9-20% Ag, 0.5-2% Cu), of alluvial origin, proved by the presence of Sn, Sb and Te embedded in the gold. The problem of provenance for prehistoric Romanian copper and bronze objects consists in linking their elemental compositional patterns to the ones of the Bronze Age regional mines from Bulgaria, Serbia or Transylvania, most likely used as ore sources for their manufacture. The studied samples present relevant traces of As, Ag, Sb, and Co, suggesting the most probable use of copper from Serbia or northern Bulgaria for their manufacture.
